An RFT test, or Renal Function Test, is a group of tests that assess the health and function of your kidneys. They measure how well your kidneys are filtering waste products from your blood and producing urine. These tests are usually performed together and may include blood tests, urine tests, or both.
Doctors may order RFT tests to:
- Diagnose kidney disease: RFTs help determine if your kidneys are functioning properly and identify any signs of damage.
- Monitor kidney function: For people with known kidney disease or risk factors like diabetes or high blood pressure, RFTs help monitor the progression of the disease and adjust treatment plans.
- Evaluate the effectiveness of treatment: RFTs can assess the effectiveness of medications or other therapies used to treat kidney disease.
Some common tests included in an RFT panel are:
- Creatinine levels: Measures the amount of creatinine, a waste product produced by muscles, in your blood.
- Blood urea nitrogen (BUN): Measures the amount of urea nitrogen, another waste product, in your blood.
- Glomerular filtration rate (eGFR): Estimates how well your kidneys filter waste products from your blood.
- Electrolyte levels: Measures the levels of sodium, potassium, and other electrolytes in your blood.
- Urine protein levels: Measures the amount of protein in your urine, which can indicate kidney damage.
RFT results can help doctors understand the health of your kidneys and guide treatment decisions. If you have any concerns about your kidney health, it is important to consult with your doctor.
